Device, method, and graphical user interface for accessing an application in a locked device

ABSTRACT

While an electronic device with a display and a touch-sensitive surface is in a locked, passcode-protected state, the device displays a lock screen user interface on the display. The lock screen user interface includes a plurality of restricted application launch icons, each restricted application launch icon corresponding to an application. The device also detects user input to activate a respective restricted application launch icon; and, in response to detecting the user input to activate the respective restricted application launch icon, starts a restricted session for a respective application that corresponds to the respective restricted application launch icon, wherein the respective application is configured to generate one or more content items while in the restricted session, and maintains the device in the locked, passcode-protected state for applications in the device other than the respective application.

RELATED APPLICATIONS

This application claims priority to U.S. Provisional Application Ser. No. 61/493,506, filed Jun. 5, 2011, entitled “Device, Method, and Graphical User Interface for Accessing an Application in a Locked Device,” which is incorporated herein by reference in its entirety.

This application is related to U.S. application Ser. No. 13/243,326, filed Sep. 23, 2011, entitled “Device, Method, and Graphical User Interface for Accessing an Application in a Locked Device,” which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

This relates generally to electronic devices with touch-sensitive surfaces, including but not limited to electronic devices with touch-sensitive surfaces that enable restricted access to an application while the device is locked.

BACKGROUND

The use of portable devices with touch-sensitive surfaces as input devices has increased significantly in recent years. Such portable devices have greatly increased the number of content generation opportunities for users, including taking pictures or writing down notes, contact information, or appointments, just to name a few examples. Often, in such content generation opportunities, time is critical, as a user may want to take advantage of a fresh memory or a fleeting event.

But existing methods for accessing applications are slow and a hindrance to fast content generation, particularly when the device is in a locked, passcode-protected state. Accessing applications on a device while the device is locked requires multiple steps, which prevent immediate use of applications when rapid use is beneficial or desired. Further, certain applications such as the camera application require multiple hardware and software operations during startup. These multiple operations may delay the moment when the application is ready to use, and thus also hinder quick content generation.

SUMMARY

Accordingly, there is a need for electronic devices with faster, more efficient methods and interfaces for quickly accessing an application in a locked device, without unlocking other applications on the device. Such methods and interfaces may complement or replace conventional methods for accessing an application in a locked device. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface.

DESCRIPTION OF EMBODIMENTS

Typically, accessing an application in a locked device takes several steps and corresponding user inputs. For example, the steps may include unlocking the device with a passcode, navigating to an icon corresponding to the application, and activating the icon. While having to unlock the device with a passcode first provides device security, there are times when having to unlock the device first to access an application is a hindrance, such as during content generation opportunities where time is critical. The embodiments described below enable a user to access to one of several applications without the user entering the passcode; the passcode protection is bypassed. When the device is locked, an interface with multiple icons corresponding to respective applications is displayed. When one of these icons is activated, the corresponding application is started in a restricted session and the device remains locked with respect to the other applications. This provides for fast application access (e.g., by bypassing passcode input) and also maintains device security in light of the fast application access (e.g., by placing restrictions on use of the application and maintaining the device in a locked state with respect to other applications). Fast application access when the device is in a locked, passcode protected state is particular useful for portable devices (e.g., smart phones), but can also be used with other devices (e.g., desktop computers).

Typically, applications on a device are accessed when a device is unlocked, e.g., after the user has entered a passcode to unlock the device. However, when application access with bypass of the passcode protection is allowed, there is a risk that content may be exposed to unauthorized persons. Some of the embodiments described below reduce such risk by restricting the content that an application may present based on predefined restricted session access criteria.

When a camera application is launched, several operations are performed in order to start up the hardware and software components needed to run the camera application. Some of the embodiments described below provide a faster way to launch a camera application. By performing the various operations involved in launching the camera application concurrently, there is less delay between the user input to launch the camera application and the camera application being ready for use.

Below, FIGS. 1A-1B, 2, 3, and 10-12 provide a description of exemplary devices. FIGS. 4A-4B and 5A-5O illustrate exemplary user interfaces for accessing an application on a locked device. FIGS. 7A-7C are flow diagrams illustrating a method of accessing one restricted application in a plurality of restricted applications on a locked device. FIG. 8 is a flow diagram illustrating a method of presenting content generated in a restricted application session. FIG. 9 is a flow diagram illustrating a method of launching a camera application. The user interfaces in FIGS. 5A-5O are used to illustrate the processes in FIGS. 7A-7C and 8.

The other input control devices 116 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 160 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2) may include an up/down button for volume control of speaker 111 and/or microphone 113. The one or more buttons may include a push button (e.g., 206, FIG. 2).

Touch-sensitive display 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch screen 112. Touch screen 112 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects.

Touch screen 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch screen 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen 112. In an exemplary embodiment, a point of contact between touch screen 112 and the user corresponds to a finger of the user.

Touch screen 112 may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen 112 and display controller 156 may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 112. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.

Touch screen 112 may have a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user may make contact with touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.

Device 100 also includes power system 162 for powering the various components. Power system 162 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 100 may also include one or more optical sensors 164. FIG. 1A shows an optical sensor coupled to optical sensor controller 158 in I/O subsystem 106. Optical sensor 164 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 164 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor 164 may capture still images or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch screen display 112 on the front of the device, so that the touch screen display may be used as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display.

Device 100 may also include one or more proximity sensors 166. FIG. 1A shows proximity sensor 166 coupled to peripherals interface 118. Alternately, proximity sensor 166 may be coupled to input controller 160 in I/O subsystem 106. In some embodiments, the proximity sensor turns off and disables touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

Device 100 may also include one or more accelerometers 168. FIG. 1A shows accelerometer 168 coupled to peripherals interface 118. Alternately, accelerometer 168 may be coupled to an input controller 160 in I/O subsystem 106. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 100 optionally includes, in addition to accelerometer(s) 168, a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 100.

In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, graphics module (or set of instructions) 132, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, and applications (or sets of instructions) 136. Furthermore, in some embodiments memory 102 stores device/global internal state 157, as shown in FIGS. 1A and 3. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 112; sensor state, including information obtained from the device's various sensors and input control devices 116; and location information concerning the device's location and/or attitude. Further, in some embodiments, memory 102 stores camera roll 159 and digital image pipeline 161.

Operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Inc.) devices.

Contact/motion module 130 may detect contact with touch screen 112 (in conjunction with display controller 156) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

Contact/motion module 130 may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event.

Graphics module 132 includes various known software components for rendering and displaying graphics on touch screen 112 or other display, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.

In some embodiments, graphics module 132 stores data representing graphics to be used. Each graphic may be assigned a corresponding code. Graphics module 132 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 156.

Text input module 134, which may be a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, browser 147, and any other application that needs text input).

GPS module 135 determines the location of the device and provides this information for use in various applications (e.g., to telephone 138 for use in location-based dialing, to camera 143 as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules may be combined or otherwise re-arranged in various embodiments. In some embodiments, memory 102 may store a subset of the modules and data structures identified above. Furthermore, memory 102 may store additional modules and data structures not described above.

In some embodiments, device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 100, the number of physical input control devices (such as push buttons, dials, and the like) on device 100 may be reduced.

The predefined set of functions that may be performed exclusively through a touch screen and/or a touchpad include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 100 to a main, home, or root menu from any user interface that may be displayed on device 100. In such embodiments, the touchpad may be referred to as a “menu button.” In some other embodiments, the menu button may be a physical push button or other physical input control device instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 102 (in FIG. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g., in operating system 126) and a respective application 136-1 (e.g., any of the aforementioned applications 137-151, 155, 380-390).

Event sorter 170 receives event information and determines the application 136-1 and application view 191 of application 136-1 to which to deliver the event information. Event sorter 170 includes event monitor 171 and event dispatcher module 174. In some embodiments, application 136-1 includes application internal state 192, which indicates the current application view(s) displayed on touch sensitive display 112 when the application is active or executing. In some embodiments, device/global internal state 157 is used by event sorter 170 to determine which application(s) is (are) currently active, and application internal state 192 is used by event sorter 170 to determine application views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additional information, such as one or more of: resume information to be used when application 136-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 136-1, a state queue for enabling the user to go back to a prior state or view of application 136-1, and a redo/undo queue of previous actions taken by the user.

Event monitor 171 receives event information from peripherals interface 118. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display 112, as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I/O subsystem 106 or a sensor, such as proximity sensor 166, accelerometer(s) 168, and/or microphone 113 (through audio circuitry 110). Information that peripherals interface 118 receives from I/O subsystem 106 includes information from touch-sensitive display 112 or a touch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripherals interface 118 at predetermined intervals. In response, peripherals interface 118 transmits event information. In other embodiments, peripheral interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit view determination module 172 and/or an active event recognizer determination module 173.

Hit view determination module 172 provides software procedures for determining where a sub-event has taken place within one or more views, when touch sensitive display 112 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected may correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected may be called the hit view, and the set of events that are recognized as proper inputs may be determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (i.e., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

Event dispatcher module 174 dispatches the event information to an event recognizer (e.g., event recognizer 180). In embodiments including active event recognizer determination module 173, event dispatcher module 174 delivers the event information to an event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores in an event queue the event information, which is retrieved by a respective event receiver module 182.

In some embodiments, operating system 126 includes event sorter 170. Alternatively, application 136-1 includes event sorter 170. In yet other embodiments, event sorter 170 is a stand-alone module, or a part of another module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 191 of the application 136-1 includes one or more event recognizers 180. Typically, a respective application view 191 includes a plurality of event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 136-1 inherits methods and other properties. In some embodiments, a respective event handler 190 includes one or more of: data updater 176, object updater 177, GUI updater 178, and/or event data 179 received from event sorter 170. Event handler 190 may utilize or call data updater 176, object updater 177 or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views 191 includes one or more respective event handlers 190. Also, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g., event data 179) from event sorter 170, and identifies an event from the event information. Event recognizer 180 includes event receiver 182 and event comparator 184. In some embodiments, event recognizer 180 also includes at least a subset of: metadata 183, and event delivery instructions 188 (which may include sub-event delivery instructions).

Event receiver 182 receives event information from event sorter 170. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch the event information may also include speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

Event comparator 184 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 184 includes event definitions 186. Event definitions 186 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (187-1), event 2 (187-2), and others. In some embodiments, sub-events in an event 187 include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (187-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (touch end) for a predetermined phase. In another example, the definition for event 2 (187-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display 112, and lift-off of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

In some embodiments, event definition 187 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 184 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display 112, when a touch is detected on touch-sensitive display 112, event comparator 184 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler associated with the sub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event 187 also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series of sub-events do not match any of the events in event definitions 186, the respective event recognizer 180 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata 183 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate how event recognizers may interact with one another. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates event handler 190 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 180 delivers event information associated with the event to event handler 190. Activating an event handler 190 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 180 throws a flag associated with the recognized event, and event handler 190 associated with the flag catches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates the telephone number used in contacts module 137, or stores a video file used in video player module 145. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 176 creates a new user-interface object or updates the position of a user-interface object. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends it to graphics module 132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of a respective application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 100 with input-devices, not all of which are initiated on touch screens, e.g., coordinating mouse movement and mouse button presses with or without single or multiple keyboard presses or holds, user movements taps, drags, scrolls, etc., on touch-pads, pen stylus inputs, movement of the device, oral instructions, detected eye movements, biometric inputs, and/or any combination thereof, which may be utilized as inputs corresponding to sub-events which define an event to be recognized.

FIG. 2 illustrates a portable multifunction device 100 having a touch screen 112 in accordance with some embodiments. The touch screen may display one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user may select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure) or one or more styluses 203 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture may include one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 100. In some embodiments, inadvertent contact with a graphic may not select the graphic. For example, a swipe gesture that sweeps over an application icon may not select the corresponding application when the gesture corresponding to selection is a tap.

Device 100 may also include one or more physical buttons, such as “home” or menu button 204. As described previously, menu button 204 may be used to navigate to any application 136 in a set of applications that may be executed on device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen 112.

In one embodiment, device 100 includes touch screen 112, menu button 204, push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, Subscriber Identity Module (SIM) card slot 210, headset jack 212, and docking/charging external port 124. Push button 206 may be used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device 100 also may accept verbal input for activation or deactivation of some functions through microphone 113.

FIG. 3 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 300 need not be portable. In some embodiments, device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 300 typically includes one or more processing units (CPU's) 310, one or more network or other communications interfaces 360, memory 370, and one or more communication buses 320 for interconnecting these components. In some embodiments, processing unit(s) 310 include an image signal processor and a dual-core or multi-core processor. Communication buses 320 may include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 300 includes input/output (I/O) interface 330 comprising display 340, which is typically a touch screen display. I/O interface 330 also may include a keyboard and/or mouse (or other pointing device) 350 and touchpad 355. Device 300 also includes optical sensor(s) 164 and optical sensor(s) controller 158. Memory 370 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and may include non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory 370 may optionally include one or more storage devices remotely located from CPU(s) 310. In some embodiments, memory 370 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 102 of portable multifunction device 100 (FIG. 1), or a subset thereof. Furthermore, memory 370 may store additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 may store drawing module 380, presentation module 382, word processing module 384, website creation module 386, disk authoring module 388, and/or spreadsheet module 390, while memory 102 of portable multifunction device 100 (FIG. 1) may not store these modules.

Each of the above identified elements in FIG. 3 may be stored in one or more of the previously mentioned memory devices. Each of the above identified modules corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules may be combined or otherwise re-arranged in various embodiments. In some embodiments, memory 370 may store a subset of the modules and data structures identified above. Furthermore, memory 370 may store additional modules and data structures not described above.

Attention is now directed towards embodiments of user interfaces (“UI”) that may be implemented on portable multifunction device 100.

FIG. 4A illustrates an exemplary user interface for a menu of applications on portable multifunction device 100 in accordance with some embodiments. Similar user interfaces may be implemented on device 300. In some embodiments, user interface 400 includes the following elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),         such as cellular and Wi-Fi signals;     -   Time 404;     -   Bluetooth indicator 405;     -   Battery status indicator 406;     -   Tray 408 with icons for frequently used applications, such as:         -   Phone 138, which may include an indicator 414 of the number             of missed calls or voicemail messages;         -   E-mail client 140, which may include an indicator 410 of the             number of unread e-mails;         -   Browser 147; and         -   Video and music player 152, also referred to as iPod             (trademark of Apple Inc.) module 152; and     -   Icons for other applications, such as:         -   IM 141;         -   Image management 144;         -   Camera 143;         -   Weather 149-1;         -   Stocks 149-2;         -   Workout support 142;         -   Calendar 148;         -   Alarm clock 149-4;         -   Map 154;         -   Notes 153;         -   Settings 412, which provides access to settings for device             100 and its various applications 136; and         -   Online video module 155, also referred to as YouTube             (trademark of Google Inc.) module 155.

FIG. 4B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from the display 450 (e.g., touch screen display 112). Although many of the examples which follow will be given with reference to inputs on touch screen display 112 (where the touch sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in FIG. 4B. In some embodiments the touch sensitive surface (e.g., 451 in FIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) that corresponds to a primary axis (e.g., 453 in FIG. 4B) on the display (e.g., 450). In accordance with these embodiments, the device detects contacts (e.g., 460 and 462 in FIG. 4B) with the touch-sensitive surface 451 at locations that correspond to respective locations on the display (e.g., in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470). In this way, user inputs (e.g., contacts 460 and 462, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 451 in FIG. 4B) are used by the device to manipulate the user interface on the display (e.g., 450 in FIG. 4B) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods may be used for other user interfaces described herein.

User Interfaces and Associated Processes

Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on an electronic device with a display and a touch-sensitive surface, such as device 300 or portable multifunction device 100.

FIGS. 5A-5O illustrate exemplary user interfaces for accessing an application on a locked device in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in FIGS. 7A-7C and 8.

FIG. 5A illustrates locked device interface 500-A displayed on touch screen 112 of device 100. Locked device interface 500-A may be displayed when a physical button (e.g., push button 206, home or menu button 204) on device 100 is activated by a user while device 100 is in a locked state. Locked device interface 500-A may include a message informing the users that the device is locked and other information.

Locked device interface 500-A may also include user interface objects for unlocking the device or accessing one or more applications. For example, locked device interface 500-A includes unlock image object 502 in virtual channel 504. Device 100 may be unlocked by dragging unlock image object 502 across channel 504, from one end to the other, using a gesture (e.g., dragging gesture 505). If device 100 is password-protected, when object 502 is dragged across channel 504, password entry user interface 508 is displayed, as shown in FIG. 5B. The user may use keypad 509 to enter a password. If the correct password is entered, device 100 is unlocked and a user interface with a menu of applications (e.g., user interface 400, FIG. 4A) is displayed on touch screen 112.

Returning to FIG. 5A and referring to FIG. 5C as well, also displayed in locked device interface 500-A are multiple icons 506 corresponding to respective applications. These respective applications are particular applications (e.g., contacts 137, calendar 148, notes 153, camera 143, voice/audio recorder application 163 (e.g., a “voice memos” application)) that may be accessed in a restricted session or restricted mode while device 100 is locked (and thus device 100 remains locked with respect to the other applications). When a respective application is accessed in a restricted session or restricted mode, the application may have different and/or reduced functionality and/or rights than when the application is accessed while device 100 is unlocked.

In FIGS. 5A and 5C, icon 506-A corresponds to notes application 153. Icon 506-B corresponds to contacts application 137. Icon 506-C corresponds to calendar application 148. Icon 506-D corresponds to voice/audio recorder application 163. Icon 510-E corresponds to camera application 143.

A respective application icon 506 may be activated by performance of a gesture (e.g., a tap gesture) on the respective icon 506. In response to the detection of a gesture on a respective icon 506, device 100 starts a restricted session for the corresponding application and password entry interface 508 is bypassed.

For example, in response to the detection of gesture 510-A on icon 506-A (FIG. 5C), new note entry user interface 511 of notes application 153 is displayed on touch screen 112, as shown in FIG. 5D. New note entry user interface 511 includes text entry area 512 and keyboard 514. A user may enter a textual note using keyboard 514, and the entered text is displayed in text entry area 512. Also included in new note entry user interface 511 are navigation icon 518 and “done” icon 516. In some embodiments, when a gesture (e.g., gesture 522) is detected on “done” icon 516, keyboard 514 is dismissed so that the user can view more of the newly created note. In some embodiments, when a gesture (e.g., gesture 524) is detected on navigation icon 518, notes list interface 526 (FIG. 5E) of notes application 153 is displayed while still in the restricted session.

Notes list interface 526 includes a listing of zero or more notes 530 that are generated by notes application 153 (e.g., created or saved by notes application 153) and which satisfy one or more predefined presentation criteria. In response to selection of respective note 530 (e.g., by performing a gesture on the respective note 530 in notes list interface 526, such as a finger tap gesture), an interface similar to new note entry user interface 511 is displayed, where the contents of the respective note 530 are displayed in text entry area 512. Also included in notes list interface 526 is new item icon 528. In response to the detection of a gesture (e.g., gesture 532) on new note icon 528, new note entry user interface 511 is displayed while still in the restricted session and a new note may be created.

The notes 530 that are displayed or presented in notes list interface 526 satisfy one or more predefined presentation criteria. In some embodiments, the presentation criterion is that a note, in order to be presented in notes list interface 526, and thus viewable and/or editable in notes application 153 while in the restricted session, must be generated by notes application 153 while in a restricted session. In other words, only notes generated in notes application 153 in a restricted session (i.e., created in notes application 153 while device 100 is locked with respect to the other applications) are presented in notes list interface 526 while in the restricted session, whereas notes generated in notes application 153 while device 100 is unlocked are not presented in notes list interface 526, and thus are inaccessible for viewing or editing while in the restricted session. Notes generated in any restricted session are accessible for viewing and editing in notes application 153 while device 100 is unlocked.

In some embodiments, the presentation criterion goes further, in that the note must be generated in the current restricted session. Notes generated in a prior restricted session are not presented in notes list interface 526.

The notes application 153 may be deactivated, and the restricted session ended, by activating, for example, push button 206 or home/menu button 204 while new note entry user interface 511 or notes list interface 526 is displayed in the restricted session, as in FIGS. 5D and 5E, respectively. In response to activation of push button 206 or home/menu button 204, the restricted session is ended and device 100 is locked with respect to notes application 153 as well as the other applications. Activation of push button 206 or home/menu button 204 while device 100 is locked results in the display of locked device interface 500-A, as in FIG. 5A or 5C.

Returning to FIG. 5C, in response to the detection of gesture 510-B on icon 506-B, new contact entry user interface 534 of contacts application 137 is displayed on touch screen 112, as shown in FIG. 5F. New contact entry user interface 534 includes multiple fields 536 corresponding to various items of contact information and keyboard 514. A user may enter information into a field 536 using keyboard 514. Also included in new contact entry user interface 534 are “cancel” icon 538 and “done” icon 516. In some embodiments, when a gesture (e.g., gesture 537) is detected on “done” icon 516, in response to the detection of the gesture on “done” icon 516, information entered into fields 536 are saved as a contact in contacts application 137, and the newly made contact or contact list interface 540 of contacts application 137 (FIG. 5G) is displayed while still in the restricted session. When a gesture is detected on cancel icon 538, information entered into fields 536 is not saved (i.e., new contact creation is cancelled). In some embodiments, in response to the gesture on cancel icon 538, contact list interface 540 of contacts application 137 is displayed while still in the restricted session. In some other embodiments, in response to the gesture on cancel icon 538, contacts application 137 is deactivated and the restricted session is ended.

Contact list interface 540 in the restricted session includes a listing of zero or more contacts 542 that are generated by contacts application 137 (e.g., created or saved by contacts application 137) and which satisfy one or more predefined presentation criteria. In response to selection of a respective contact 542 (e.g., by performing a gesture on the respective contact 542 in contacts list interface 540), information for the respective contact 542 is displayed. Also included in contact list interface 540 is new item icon 528. In response to the detection of a gesture (e.g., gesture 544) on new item icon 528, new contact entry user interface 534 is displayed while still in the restricted session and a new contact may be created.

The contacts 542 that are displayed or presented in contact list interface 540 satisfy one or more predefined presentation criteria. In some embodiments, the presentation criterion is that a contact, in order to be presented in contact list interface 540, and thus viewable and/or editable in contacts application 137 while in the restricted session, must be generated by contacts application 137 while in a restricted session. In other words, only contacts generated in contacts application 137 in a restricted session (i.e., created in contacts application 137 while device 100 is locked with respect to the other applications) are presented in contact list interface 540 while in the restricted session, and contacts generated in contacts application 137 while device 100 is unlocked are not presented in contact list interface 540, and thus are inaccessible for viewing or editing while in a restricted session. Contacts generated in any restricted session are accessible for viewing and editing in contacts application 137 while device 100 is unlocked.

In some embodiments, the presentation criterion goes further, in that the contact must be generated in the current restricted session. Contacts generated in a prior restricted session are not presented in contact list interface 540.

The contacts application 137 may be deactivated, and the restricted session ended, by activating, for example, push button 206 or home/menu button 204 while new contact entry user interface 534 or contact list interface 540 is displayed in the restricted session, as in FIGS. 5F and 5G, respectively. In response to activation of push button 206 or home/menu button 204, the restricted session is ended and device 100 is locked with respect to contacts application 137 as well as to other applications. Activation of push button 206 or home/menu button 204 while device 100 is locked results in the display of locked device interface 500-A, as in FIG. 5A or 5C.

Returning to FIG. 5C, in response to the detection of gesture 510-C on icon 506-C, new calendar event user interface 546 of calendar application 148 is displayed on touch screen 112, as shown in FIG. 5H. New calendar event user interface 546 includes multiple fields 548 corresponding to various items of calendar event information and keyboard 514. A user may enter information into a field 548 using keyboard 514. Also included in new calendar event user interface 546 are “cancel” icon 538 and “done” icon 516. When a gesture (e.g., gesture 550) is detected on “done” icon 516, in response to the detection of the gesture on “done” icon 516, information entered into fields 548 are saved as a calendar event in calendar application 148, and the newly created calendar event or calendar events interface 552 (FIG. 5I) of calendar application 148 is displayed while still in the restricted session. When a gesture is detected on cancel icon 538, in response to the detection of the gesture on cancel icon 538, information entered into fields 548 is not saved (i.e., new calendar event creation is cancelled). In some embodiments, in response to the gesture on cancel icon 538, calendar events interface 552 of calendar application 148 is displayed while still in the restricted session. In some other embodiments, in response to the gesture on cancel icon 538, calendar application 148 is deactivated and the restricted session is ended.

Calendar events interface 552 includes a listing of zero or more calendar events 554 that are generated by calendar application 148 (e.g., created or saved by calendar application 148) and which satisfy one or more predefined presentation criteria. In response to selection of a respective event 554 (e.g., by performing a gesture on the respective event 554 in calendar events interface 552), information for the respective event 554 is displayed. Also included in calendar events interface 552 is new item icon 528. In response to the detection of a gesture (e.g., gesture 556) on new item icon 528, new calendar event user interface 546 is displayed while still in the restricted session and a new event may be created.

The events 554 that are displayed or presented in calendar events interface 552 satisfy one or more predefined presentation criteria. In some embodiments, the presentation criterion is that an event, in order to be presented in calendar events interface 552, and thus viewable and/or editable in calendar application 148 while in the restricted session, must be generated by calendar application 148 while in a restricted session. In other words, only events generated in calendar application 148 in a restricted session (i.e., created in calendar application 148 while device 100 is locked with respect to the other applications) are presented in calendar events interface 552 while in the restricted session, and events generated in calendar application 148 while device 100 is unlocked are not presented in calendar events interface 552, and thus are inaccessible for viewing or editing while in a restricted session. Events generated in any restricted session are accessible for viewing and editing in calendar application 148 while device 100 is unlocked.

In some embodiments, the presentation criterion goes further, in that the event must be generated in the current restricted session. Events generated in a prior restricted session are not presented in calendar events interface 552.

The calendar application 148 may be deactivated, and the restricted session ended, by activating, for example, push button 206 or home/menu button 204 while new calendar event user interface 546 or calendar events interface 552 is displayed in the restricted session, as in FIGS. 5H and 5I, respectively. In response to activation of push button 206 or home/menu button 204, the restricted session is ended and device 100 is locked with respect to calendar application 148 as well as to other applications. Activation of push button 206 or home/menu button 204 while device 100 is locked results in the display of locked device interface 500-A, as in FIG. 5A or 5C.

Returning to FIG. 5C, in response to the detection of gesture 510-D on icon 506-D, new voice recording user interface 558 of voice/audio recorder application 163 is displayed on touch screen 112, as shown in FIG. 5J. New voice recording user interface 558 includes “record” icon 560 and “recordings” icon 562. A user begins recording by performing a gesture (e.g., a tap gesture) on “record” icon 560 and then begin speaking or making sounds. The “record” icon 560 becomes a pause icon and “recordings” icon becomes a stop icon. The user may pause the recording by performing a gesture on the pause icon. The user may stop the recording (and save the recording as an audio file) by performing a gesture on the stop icon, at which point the pause and stop icons revert back to “record” icon 560 and “recordings” icon 562, respectively.

When a gesture (e.g., a tap gesture) is detected on “recordings” icon 562, in response to the detection of the gesture on “recordings” icon 562, recordings interface 564 of voice/audio recorder application 163 is displayed while still in the restricted session, as shown in FIG. 5K.

Recordings interface 564 includes a listing of zero or more recordings 566 that are generated by voice/audio recorder application 163 (e.g., created or saved by voice/audio recorder application 163) and which satisfy one or more predefined presentation criteria. In response to selection of a respective recording 566 (e.g., by performing a gesture on the respective recording 566 in recordings interface 564), the respective recording 566 may be played back, shared, or deleted. Also included in recordings interface 564 is “done” icon 516. In response to the detection of a gesture (e.g., a tap gesture) on “done” icon 516, new voice recording user interface 558 is displayed while still in the restricted session and a new recording may be created.

The recordings 566 that are displayed or presented in recordings interface 564 satisfy one or more predefined presentation criteria. In some embodiments, the presentation criterion is that a recording, in order to be presented in recordings interface 564, and thus viewable and/or editable in voice/audio recorder application 163 while in the restricted session, must be generated by voice/audio recorder application 163 while in a restricted session. In other words, only recordings generated in voice/audio recorder application 163 in a restricted session (i.e., created in voice/audio recorder application 163 while device 100 is locked with respect to the other applications) are presented in recordings interface 564 while in the restricted session, and recordings generated in voice/audio recorder application 163 while device 100 is unlocked are not presented in recordings interface 564, and thus are inaccessible for playback or other manipulation while in a restricted session. Recordings generated in any restricted session are accessible for playback or other manipulation in voice/audio recorder application 163 while device 100 is unlocked.

In some embodiments, the presentation criterion goes further, in that the recording must be generated in the current restricted session. Recordings generated in a prior restricted session are not presented in recordings interface 564.

Voice/audio recorder application 163 may be deactivated, and the restricted session ended, by activating, for example, push button 206 or home/menu button 204 while new voice recording user interface 558 or recordings interface 564 is displayed in the restricted session, as in FIGS. 5J and 5K, respectively. In response to activation of push button 206 or home/menu button 204, the restricted session is ended and device 100 is locked with respect to voice/audio recorder application 163 as well as to other applications. Activation of push button 206 or home/menu button 204 while device 100 is locked results in the display of locked device interface 500-A, as in FIG. 5A or 5C.

Returning to FIG. 5C, in response to the detection of gesture 510-E on icon 506-E, camera interface 568 of camera application 143 is displayed on touch screen 112, as shown in FIG. 5L. Camera interface 568 includes viewfinder area 570, shutter icon 572, image/video toggle switch 574, and camera roll icon 576. When the camera interface 568 is activated, a live image preview 577 is displayed in viewfinder area 570. In response to the detection of gesture (e.g., gesture 578) on shutter icon 572, a still image is captured and saved into camera roll 159, and a thumbnail preview of the just-captured image is displayed in camera roll icon 576. In response to activation of toggle switch 572, camera application 143 switches between still image capture mode and video capture mode (while still in the restricted session).

In response to the detection of a gesture (e.g., gesture 580) on camera roll icon 576, camera roll image viewer interface 582 of camera application 143 is displayed along with the image(s) 584 in camera roll 159 that satisfy one or more predefined presentation criteria, as shown in FIG. 5M. Camera roll image viewer interface 582 includes controls 586 for browsing through images in camera roll 159 that satisfy the presentation criteria, starting a slideshow of said images, or deleting a currently displayed image. Camera roll image viewer interface 582 also includes “done” icon 516 and navigation icon 588. In response to the detection of a gesture (e.g., gesture 583) on “done” icon 516, display of camera roll image viewer interface 582 is replaced by display of camera interface 568, as in FIG. 5L. In response to the detection of a gesture (e.g., gesture 589) on navigation icon 588, display of camera roll image viewer interface 582 is replaced by display of camera roll thumbnails interface 590 of camera application 143, as shown in FIG. 5N.

Camera roll thumbnails interface 590 includes zero or more thumbnails 592 of images in camera roll 159 that are captured by camera application 143 and which satisfy the one or more predefined presentation criteria. In response to selection of a thumbnail 592 (e.g., by performing a gesture on the respective thumbnail 592 in thumbnails interface 590), the image corresponding to the selected thumbnail 592 is displayed in camera roll image viewer interface 582. Also included in thumbnails interface 590 are “done” icon 516 and type selection icons 594. In response to the detection of a gesture (e.g., a tap gesture) on “done” icon 516, camera interface 568 is displayed while still in the restricted session and a new image may be captured. In response to selection of a type selection icon (“all,” “photos,” “videos”), thumbnails 592 displayed in thumbnails interface 590 may be switched amongst both photos (still images) and videos, just photos, or just videos.

The images (e.g., image 584) and thumbnails 592 that are displayed or presented in image viewer interface 582 and thumbnails interface 590, respectively, satisfy one or more predefined presentation criteria. In some embodiments, the presentation criterion is that an image (or for a thumbnail, the image corresponding to the thumbnail), in order to be presented in image viewer interface 582 and thumbnails interface 590 while in the restricted session, must be generated (captured) by camera application 143 while in a restricted session. In other words, only images captured in camera application 143 in a restricted session (i.e., captured in camera application 143 while device 100 is locked with respect to the other applications) and corresponding thumbnails are presented in image viewer interface 582 and thumbnails interface 590, respectively, while in the restricted session, and images generated in camera application 143 while device 100 is unlocked and corresponding thumbnails are not presented in image viewer interface 582 and thumbnails interface 590, and thus are inaccessible for viewing while in a restricted session. Images captured in any restricted session, and corresponding thumbnails, are accessible for viewing in camera application 143 while device 100 is unlocked. The presentation criteria are further described below with reference to FIG. 6.

Camera application 143 may be deactivated, and the restricted session ended, by activating, for example, push button 206 or home/menu button 204 while image viewer interface 582 or thumbnails interface 590 is displayed in the restricted session, as in FIGS. 5M and 5N, respectively. In response to activation of push button 206 or home/menu button 204, the restricted session is ended and device 100 is locked with respect to camera application 143 as well as to other applications. Activation of push button 206 or home/menu button 204 while device 100 is locked results in the display of locked device interface 500-A, as in FIG. 5A or 5C.

It should be appreciated that while FIGS. 5L thru 5N were described above with respect to still images, the description of these figures apply analogously to videos.

Depending on the embodiment, the icons or buttons for accessing applications from locked device screen 500 may be presented in other ways, and/or the procedure for accessing the applications in restricted sessions varies. For example, FIG. 5O illustrates an alternative locked device screen 500-B. Icons corresponding to notes application 153, contacts application 137, calendar application 148, voice/audio recorder application 163, and camera application 143 are slider objects 598-A thru 598-E, respectively, in channels 5100-A thru 5100-E, respectively. To access an application from locked device screen 500-B, the corresponding slider object is dragged across its corresponding channel. For example, gesture 5102 is detected dragging slider object 598-E, corresponding to camera application 143, across channel 5100-E. In response to completion of the dragging, camera interface 568 is displayed as in FIG. 5L. In some other embodiments, other ways of presenting the icons and/or of accessing the applications from the locked device screen include presenting the icons corresponding to the applications as icons that change slider object 502 into a slider object for activating a corresponding application.

In some embodiments, when locked device screen 500-A or 500-B is displayed, icons 506 (FIG. 5A) or slider objects 598 (FIG. 5O), respectively, may be hidden pending additional input. For example, home/menu button 204 may be pressed twice (e.g., as in a double click) to activate display of icons 506 or slider objects 598.

In some embodiments, more or less icons 506 may be displayed in locked device interface 500-A than as shown in FIG. 5A or 5C. For example, a user may, in an options configuration interface, specify which applications are to be accessible when device 100 is locked, and thus the corresponding icons are displayed in locked device interface 500-A.

FIG. 6 illustrates example timelines of image captures and presentation criteria, in accordance with some embodiments. As described above, when an application is in the restricted session, only content (e.g., images, calendar events, contacts, notes, voice recordings, etc.) captured by the application that satisfies one or more predefined presentation criteria are accessible. The timelines depicted in FIG. 6 help illustrate the application of the presentation criteria. For sake of convenience, the timelines depicted in FIG. 6 will be described with respect to capture of still images using camera application 143, but it should be appreciated that the description applies analogously to other content as well.

Timeline 602 includes current restricted session 608 for camera application 143, prior restricted session 604 for camera application 143, and period 606 during which camera application 143 was accessed while device 100 was unlocked (i.e., camera application 143 was accessed without the limitations of a restricted session) or was inactive. The current time is marked as time 610 in current restricted session 608. Images 601-A thru 601-D were captured at various times as shown in timeline 602.

In some embodiments, the presentation criterion is that an image must be captured during any restricted session in order to be accessible in the current restricted session. Under this criterion, images 601-B and 601-C are inaccessible at current time 610 as they were captured outside of a restricted session.

In some embodiments the criterion is that an image must be captured during the current restricted session in order to be accessible in the current restricted session. Under this criterion, images 601-A thru 601-C are inaccessible at current time 610 as they were captured outside of the current restricted session.

In some embodiments, the criterion is that an image must be captured within a predefined amount of time from current time 610, regardless of whether the image was captured in a restricted session or not, in order to be accessible in the current restricted session. In timeline 602, the predefined amount of time is interval 612. Under this criterion, in timeline 602, images 601-C and 601-D are accessible at current time 610 but images 601-A and 601-B are not. If the predefined amount of time is longer, as in timeline 614, which is the same as timeline 602 except that interval 612 is replaced by longer interval 616, then images 601-A thru 601-D are all accessible.

In some embodiments, the criteria are that an image must be captured within a predefined amount of time from current time 610 and be captured in a restricted session, in order to be accessible in the current restricted session. Under these criteria, in timeline 602, images 601-A thru 601-C are inaccessible at current time 610. In timeline 614, images 601-B and 601-C are inaccessible at current time 610.

In some embodiments, the criteria are that an image must be captured within a predefined amount of time from current time 610 and be captured in the current restricted session, in order to be accessible in the current restricted session. Under these criteria, in timeline 602 or 614 images 601-A thru image 601-C are inaccessible at current time 610.

In some embodiments, the criteria are that an image must be captured during the current restricted session and that a period of inactivity or idleness in camera application 143 after the image is captured is less than a predefined threshold. In timeline 618, images 601-D and 601-E were taken prior to current time 622 during current restricted session 620, and current restricted session 620 includes period of inactivity 624. Under the criteria, if period of inactivity 624 is greater than the predefined threshold, image 601-D is inaccessible at current time 622.

In some embodiments, in a restricted session an application has write-only rights and read rights are limited to content written (i.e., generated) in a restricted session. The criteria described above with respect to FIG. 6 may be viewed as additional limitations on the read rights.

FIGS. 7A-7C are flow diagrams illustrating a method 700 of accessing one restricted application in a plurality of restricted applications on a locked device in accordance with some embodiments. The method 700 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 700 may be combined and/or the order of some operations may be changed.

As described below, the method 700 provides a way to access one of several applications on a locked device by bypassing the password protection on the device. The method reduces the number of inputs required on the user's part when accessing an application on a locked device, thereby creating a more efficient human-machine interface. Further, enabling a user to quickly access certain applications in a restricted session on a locked device allows the user to take advantage of content generation opportunities where time is critical, yet still maintains acceptable device security.

While the device is in a locked, passcode-protected state (702), the device displays a lock screen user interface on the display (704). The lock screen user interface includes a plurality of restricted application launch icons, and each restricted application launch icon corresponds to an application. In some embodiments, the passcode is a password entered in the device (e.g., via a keyboard). In some embodiments, the passcode is a series of gestures on the touch-sensitive surface of the electronic device that are used to authenticate a user of the device. In some embodiments, a restricted application launch icon looks the same as the corresponding application launch icon that is displayed when the device is in an unlocked state. In some embodiments, to indicate that the corresponding application will open in a restricted session, a restricted application launch icon has a distinct appearance from the corresponding application launch icon that is displayed when the device is in an unlocked state. In some embodiments, the restricted application launch icons include a restricted camera application launch icon that corresponds to a camera application configured to take still and/or video images. In some embodiments, the camera application can be launched in a restricted session via a hardware button on the device, such as a shutter button, in addition to or in place of launching the camera application via a restricted camera application launch icon.

For example, FIGS. 5A and 5C shows locked device interface 500-A displayed on touch screen 112. Locked device interface 500-A includes icons 506 corresponding to respective applications to be launched in respective restricted sessions.

The device detects user input to activate a respective restricted application launch icon (706). In some embodiments, the input is a gesture, such as a tap gesture or a drag gesture, on the respective restricted application launch icon. For example, in FIG. 5C, a respective gesture 510 is detected on a respective icon 506. In some embodiments, the input includes interaction with another icon (e.g., movement of slider object 502 in FIG. 5C) while the respective restricted application launch icon is highlighted or otherwise visually distinguished from the other restricted application launch icons in the plurality of restricted application launch icons.

In response to detecting the user input to activate the respective restricted application launch icon (708), the device starts a restricted session for a respective application that corresponds to the respective restricted application launch icon (710). The respective application is configured to generate one or more content items while in the restricted session. For example, in response to detection of gesture 510-A on icon 506-A, new note entry user interface 511 of notes application 153 is displayed, as shown in FIG. 5D.

Also in response to detecting the user input to activate the respective restricted application launch icon (708), the device maintains the device in the locked, passcode-protected state for applications in the device other than the respective application (712). Note that activating the respective application in the restricted session includes bypassing input of the passcode. Thus, the device maintains the locked, passcode-protected state for other applications in the device besides the respective application. For example, when new note entry user interface 511 of notes application 153 is displayed, as in FIG. 5D, device 100 is locked with respect to applications other than notes application 153.

In some embodiments, while the respective application is in the restricted session (714), the respective application is enabled to present one or more content items generated by the respective application while in the restricted session (716), and the respective application is disabled from presenting any content items in the respective application that were not generated while in the restricted session (718). In some embodiments, one of the criteria described below in method 800 is used to determine the conditions in which the respective application is disabled from presenting content items generated by the respective application. For brevity, those criteria are not repeated here.

In some embodiments, the plurality of restricted application launch icons include one or more of a restricted note taking application launch icon, a restricted calendar application launch icon, a restricted contact list application launch icon, and a restricted voice recorder application launch icon (720). For example, in FIG. 5C, icons 506 include icon 506-A corresponding to notes application 153, icon 506-B corresponding to contacts application 137, icon 506-C corresponding to calendar application 148, and icon 506-D corresponding to voice/audio recorder application 163. Also included is icon 506-E corresponding to camera application 143.

In some embodiments, the respective restricted application launch icon is a restricted note taking application launch icon, the respective application is a note taking application, and the note taking application is configured to generate notes while in the restricted session (722). For example, icon 506-A corresponds to notes application 153, and notes application 153 is configured to generate notes in the restricted session (e.g., in response to user inputs received in new note entry user interface 511).

In some embodiments, while the note taking application is in the restricted session (724), the note taking application is enabled to display one or more notes generated by the note taking application while in the restricted session (726), and the note taking application is disabled from displaying any notes in the note taking application that were not generated while in the restricted session (728). In some embodiments, one of the criteria described below in method 800 is used to determine the conditions in which the note taking application is disabled from presenting notes generated by the note taking application. For brevity, those criteria are not repeated here.

In some embodiments, the respective restricted application launch icon is a restricted calendar application launch icon, the respective application is a calendar application, and the calendar application is configured to generate calendar events while in the restricted session (730). For example, icon 506-C corresponds to calendar application 148, and calendar application 148 is configured to generate calendar events in the restricted session (e.g., in response to user inputs received in new calendar event user interface 546).

While the calendar application is in the restricted session (732), the calendar application is enabled to display one or more calendar events generated by the calendar application while in the restricted session (734), and the calendar application is disabled from displaying any calendar events in the calendar application that were not generated while in the restricted session (736). In some embodiments, one of the criteria described below in method 800 is used to determine the conditions in which the calendar application is disabled from presenting calendar events generated by the calendar application. For brevity, those criteria are not repeated here.

In some embodiments, the respective restricted application launch icon is a restricted contact list application launch icon, the respective application is a contact list application, and the contact list application is configured to generate new contact list entries while in the restricted session (738). For example, icon 506-B corresponds to contacts application 137, and contacts application 137 is configured to generate contact entries in the restricted session (e.g., in response to user inputs received in new contact entry user interface 534).

In some embodiments, while the contact list application is in the restricted session (740), the contact list application is enabled to display one or more contact list entries generated by the contact list application while in the restricted session (742), and the contact list application is disabled from displaying any contact list entries in the contact list application that were not generated while in the restricted session (744). In some embodiments, one of the criteria described below in method 800 is used to determine the conditions in which the contacts application is disabled from presenting contact entries generated by the contacts application. For brevity, those criteria are not repeated here.

In some embodiments, the respective restricted application launch icon is a restricted voice recorder application launch icon, the respective application is a voice recorder application, and the voice recorder application is configured to generate voice recordings while in the restricted session (746). For example, icon 506-D corresponds to voice/audio recorder application 163, and voice/audio recorder application 163 is configured to generate voice recordings in the restricted session (e.g., in response to user inputs received in new voice recording user interface 558).

In some embodiments, while the voice recorder application is in the restricted session (748), the voice recorder application is enabled to play one or more voice recordings generated by the voice recorder application while in the restricted session (750), and the voice recorder application is disabled from playing any voice recordings in the voice recorder application that were not generated while in the restricted session (752). In some embodiments, one of the criteria described below in method 800 is used to determine the conditions in which the voice recorder application is disabled from presenting voice recordings generated by the voice recorder application. For brevity, those criteria are not repeated here.

In some embodiments, the plurality of restricted application launch icons is user configurable (754). In some embodiments, a user can select (e.g., via a settings menu or other interface reconfiguration process) which applications can be launched in a restricted session via a corresponding restricted application launch icon on the lock screen user interface. Thus, a user can customize the lock screen user interface to show restricted application launch icons for applications that the user wants quick access to, without displaying additional icons for other applications. For example, a user may specify which applications can be launched in a restricted session on device 100, and thus specify which icons 506 are displayed on locked device interface 500-A.

Additionally, it should be noted that details of other processes described herein with respect to methods 800 and 900 (e.g., FIGS. 8 and 9 respectively) are also applicable in an analogous manner to method 700 described above with respect to FIGS. 7A-7C. For example, the respective applications described above with reference to method 700 may have one or more of the characteristics of the respective applications described herein with reference to method 800 or the camera application described herein with reference to method 900. For brevity, these details are not repeated here.

FIG. 8 is a flow diagram illustrating a method 800 of presenting content generated in a restricted application session in accordance with some embodiments. The method 800 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1) with a display, a touch-sensitive surface, and a plurality of applications. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 800 may be combined and/or the order of some operations may be changed.

As described below, the method 800 provides security to content on a locked device. When access to an application in a restricted session is allowed on a locked device, which bypasses password protection, there is a risk that device content may be exposed to unauthorized users. This method reduces such risk by restricting the content that an application may present based on predefined restricted session access criteria.

The device starts a restricted session for a first application while maintaining the device in a locked, passcode-protected state for applications in the device other than the respective application (802). Exemplary applications that may be opened in a restricted session include a note taking application, a calendar application, a contact list application, a voice recorder application and a camera application, as described above in method 700. For example, in response to detection of gesture 510-E on icon 506-E, camera interface 568 of camera application 143 is displayed, as shown in FIG. 5L; camera application 143 is started in a restricted session.

While the first application is in the restricted session (804), the device generates (e.g., creates, captures) one or more content items in the first application (806) (e.g., generating notes in notes application 153, generating calendar entries in calendar application 148, generating contact entries in contacts application 137, generating voice recordings in voice recordings application 163, or capturing images or videos in camera application 143 in response to user inputs).

The device receives a request to present one or more content items in the first application (808) (e.g., detecting a gesture on icon 518 in FIG. 5D to display notes 530, detecting a gesture on icon 538 in FIG. 5F to display contacts 542, detecting a gesture on icon 538 in FIG. 5H to display calendar events, detecting a gesture on icon 562 in FIG. 5J to display voice recordings, or detecting a gesture on icon 588 to display image thumbnails).

In response to receiving the request to present one or more content items in the first application (810), the device presents content items or representations thereof (e.g., thumbnail images or other icons representing content items) that meet restricted session access criteria for the first application (812), and does not present content items or representations thereof that fail to meet the restricted session access criteria for the first application (814). For example, in FIG. 5N, thumbnails 592 that are displayed correspond to images that meet the restricted session access criteria (e.g., captured in a restricted session), and thumbnails corresponding to images that fail to meet these criteria are excluded from display.

In some embodiments, the restricted session access criteria include that, to be presented, a content item or representation thereof was created during the restricted session for the first application (816). For example, as described above with respect to FIG. 6, a criterion may be that a content item is generated during the current restricted session. Under this criterion, in timeline 602, images 601-A thru 601-C are inaccessible at current time 610.

In some embodiments, the restricted session access criteria include that, to be presented, a content item or representation thereof was created within a predefined time of a current time (818) (e.g., within 10 minutes, 1 hour, or 1 day of the current time, independent of whether the content item was created during the restricted session for the first application, during a prior restricted session, or while the device was unlocked and the first application was operated in a normal (unrestricted) session). For example, as described above with respect to FIG. 6, if the criterion is that the content item be generated within a predefined amount of time 612 from the current time 610 without regard to whether the item was generated in a restricted session or not, in timeline 602 images 601-A and 601-B are inaccessible at current time 610 but images 601-C and 61-D are accessible at current time 610.

In some embodiments, the restricted session access criteria include that, to be presented, a content item or representation thereof was created during the restricted session for the first application and within a predefined time of a current time (820). For example, as described above with respect to FIG. 6, if the criterion is that the content item be generated within a predefined amount of time 612 from the current time 610 and be generated in the current restricted session, in timeline 602 images 601-A thru 601-C are inaccessible at current time 610 and image 601-D is accessible at current time 610.

In some embodiments, the restricted session access criteria include that, to be presented, a content item or representation thereof was created during the restricted session for the first application and a current time period of inactivity for the first application in the restricted session is less than a predefined threshold (822) (e.g., 5, 8, 10, or 15 minutes or any reasonable time period). For example, after 8 minutes of inactivity, images taken with the camera application during a restricted session can no longer be viewed in the restricted session. The user needs to unlock the device to view these images, as well as the other images previously stored on the device. Under this criterion, in timeline 618 in FIG. 6, if period of inactivity 624 is longer than the threshold, image 601-D is inaccessible at current time 622.

In some embodiments, the device deactivates the first application in the restricted session and returns the entire device to the locked, passcode-protected state when one or more deactivation conditions are met, such as detecting activation of a hardware or software button (e.g., a quit, done, or power-off button, home/menu button 204, push button 206) or detecting a time period of inactivity for the first application in the restricted session that is greater than a predefined threshold (e.g., 5, 8, 10, or 15 minutes or any reasonable time period).

Additionally, it should be noted that details of other processes described herein with respect to methods 700 and 900 (e.g., FIGS. 7A-7C and 9 respectively) are also applicable in an analogous manner to method 800 described above with respect to FIG. 8. For example, the respective applications described above with reference to method 800 may have one or more of the characteristics of the respective applications described herein with reference to method 700 or the camera application described herein with reference to method 900. For brevity, these details are not repeated here.

FIG. 9 is a flow diagram illustrating a method 900 of launching a camera application in accordance with some embodiments. The method 900 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1) with a display, a touch-sensitive surface, one or more processors, random access memory, and a camera. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 900 may be combined and/or the order of some operations may be changed.

As described below, the method 900 provides a faster way to launch a camera application. By performing the various operations involved in the launching of the camera application concurrently, there is less delay between the user input to launch the camera application and the camera application being actually ready for use.

The device detects an input to launch a camera application that controls the camera (902) (e.g., an application configured to take still images and/or video images with the camera hardware). In some embodiments, the device detects a gesture at a location on the touch-sensitive surface that corresponds to a launch icon for the camera application. In some embodiments, the device detects activation of a hardware button associated with the camera application, such as a shutter button. For example, a gesture may be detected on the icon corresponding to camera application 143 (FIG. 4A). As another example, in FIG. 5C, gesture 510-E is detected on icon 506-E corresponding to camera application 143.

In response to detecting the input to launch the camera application, the device concurrently (904) (e.g., via a dual-core or multi-core processor) loads instructions for controlling a user interface for the camera application in the random access memory (906), allocates a portion of the random access memory to instructions for a digital image pipeline (908), and initializes (e.g., powers up) one or more hardware components in the camera (910). For example, in response to the input to launch the camera application, the device loads instructions in camera module 143 for controlling the camera application user interface into the random access memory portions of memory 102, allocates a portion of random access memory to digital image pipeline 161, and powers up camera hardware components such as optical sensor(s) 164 and optical sensor(s) controller 158.

In some embodiments, initializing one or more hardware components in the camera includes initializing an image capture sensor (e.g., a CMOS or CCD image sensor chip) and an image signal processor (912). For example, initializing the hardware components includes initializing optical sensor(s) 164 and optical sensor(s) controller 158 (FIG. 1A).

When loading instructions for controlling the user interface, allocating the portion of the random access memory, and initializing one or more hardware components are complete, the device displays a live image preview in the user interface for the camera application on the display (918). The live image preview is typically displayed as soon as the last of these concurrent processes is complete. For example, when the above-described concurrent loading, allocating, and initializing are complete, live image preview 577 is displayed in viewfinder area 570, as in FIG. 5L.

In some embodiments, in response to detecting the input to launch the camera application, the device concurrently loads data corresponding to a camera roll for the camera application in the random access memory, the camera roll including images taken previously with the camera application (914); and when loading instructions for controlling the user interface, loading data corresponding to the camera roll, allocating the portion of the random access memory, and initializing one or more hardware components are complete, the device displays a live image preview in the user interface for the camera application on the display (920). In other words, the concurrent procedures described above (906, 908, 910) further include concurrent loading of data corresponding to a camera roll (e.g., camera roll 159) for the camera application in the random access memory. When procedures 906, 908, 910, and 914 are all complete, live image preview 577 is displayed in viewfinder area 570, as in FIG. 5L.

In some embodiments, the loading of data corresponding to the camera roll is performed in the background (916).

In some embodiments, the electronic device is a portable electronic device configured to operate a plurality of applications including the camera application and a phone application (922). For example, device 100 (FIG. 1A) includes multiple applications including camera application 143 and telephone application 138.

It should be noted that details of other processes described herein with respect to methods 700 and 800 (e.g., FIGS. 7A-7C and 8 respectively) are also applicable in an analogous manner to method 900 described above with respect to FIG. 9. For example, the camera application described above with reference to method 900 may have one or more of the characteristics of the respective applications described herein with reference to method 700 or 800. For brevity, these details are not repeated here.
